Precision engineering
Performance is a function of precision engineering.
The innovative design of the DPI 611 pressure system can only achieve efficient generation and precise control through the use of carefully selected materials with high tolerance machining and perfect finishes.
The choice of case material and precision moulding ensures that the DPI 611 is both rugged and weatherproof.
State-of-the-art analogue and digital microelectronics contribute both accuracy and processing power to provide a class leading pressure and electrical capability with a unique simple-to-use interface.
Documenting capabilities
The DPI 611 is a simple-to-use “everyday” tool for maintaining and calibrating pressure instruments. It also has the advanced features of the DPI 620 Genii for automating calibration procedures, calculating errors, and interfacing with PCs and calibration and maintenance systems.
- Automated calibration procedures
- PASS/FAIL error analysis
- Multi-channel data logging
- 8 GB (nominal) user memory
- Connectivity with leading calibration and maintenance software including 4Sight
Advanced features
Step and ramp mA output: Simply configured for simulating transmitter outputs into control loops, testing valve positioners, and checking safety systems. The function has programmable endpoints, manual or automatic sequencing, and the following options for quick set-up:
- % step: The step size is defined as a percentage. For example, 25% provides five test points of 4, 8, 12, 16, and 20 mA.
- Defined step: The step size is defined as a value in mA.
- Span check: Toggles between two endpoints, for example, 4 and 20 mA for checking zero and FS.
- Ramp: A linear ramp between two endpoints with programmable travel and dwell times is perfect for dynamically testing switches.
Nudge: Simply used to make a small incremental change to a mA output using up/down keys. This is great for determining trip values.
Switch test: Automates the capture of pressure switch actuation and de-actuation values and calculates the hysteresis.
Pressure leak test: This automated procedure for detecting leaks and determining leak rates has programmable settle and run times. The start and end pressures are reported along with the pressure change and leak rate.
Max/min: Captures maximum and minimum values and calculates the mean.
Relief valve: Captures the venting pressure of a relief valve.
Scaling: Scales the measured value into a process value. For example, mA expressed as a %. Flow correction is available for scaling differential flow transmitter outputs.
Pressure Resolution: Adjustable from four to seven digits; this matches the displayed value to that of the test device for easy comparison.
Help: The DPI 611 is provided with a multi-lingual quick user guide to get you up and running without delay. For convenience, the full manual is stored digitally within the instrument and can be transferred to a PC for viewing or printing. In the help application, you can also view wiring connection diagrams.
